Please talk about how the Qing government became a foreigner's court step by step based on the three treaties.

It was about 25 years from the outbreak of the Opium War in 1840 to the failure of the Taiping Heavenly Kingdom Movement in 1864. This is the primary stage of China's transformation from a feudal society to a semi-colonial and semi-feudal society.

The content and influence of Tianjin Treaty and Beijing Treaty after the Second Opium War: Russia occupied a large area of northern China.

(1) After the Opium War, Britain and other western powers forced the Qing government to sign the first batch of unequal treaties such as the treaty of nanking, and the social nature of China changed, and China began to become a semi-colonial and semi-feudal society.

(2) During the Second Opium War, the foreign powers forced the Qing government to sign the second batch of unequal treaties such as Tianjin Treaty, Beijing Treaty and Aihui Treaty. As a result, China lost more territory and sovereignty, and the degree of semi-colonization was further deepened.

(3) From 65438 to 1960s and 1970s, capitalism emerged in China, China's economic structure changed, the feudal economy gradually disintegrated, and China's economy gradually fell into the capitalist world market. In this way, China's economy presents the characteristics of semi-colonial and semi-feudal economy.

(4)1In the 1960s and 1970s, there was a crisis in China's border areas. 1883- 1885 the sino-French war gradually deepened the national crisis.

(5) During the Sino-Japanese War in the Sino-Japanese War of 1894-1895, Japan forced the Qing government to sign the treaty of shimonoseki, and the economic aggression of the great powers against China developed from commodity export to capital export. Imperialism set off a frenzy to carve up China, moving towards reunification and converging interests.

(6) After Eight-Nation Alliance's war of aggression against China, the foreign powers forced the Qing government to sign the "Xin Chou Treaty", and China society was completely plunged into the abyss of semi-colonial and semi-feudal society.
